Q:Where are the mechanical pressurization air supply facilities set up?

The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.

Q:What are the main functions of construction equipment monitoring system?

This belongs to information management engineering. The control part is the "heart" and "brain" of the whole system. It is the command center to realize the function of the whole system. The control part is mainly composed of the main console (some systems also have a secondary console). The main function of the total console: video signal amplification and signal distribution, image correction and compensation, image signal and image signal (including switching or voice signals) record, cameras and auxiliary components (such as camera, PTZ, shield) control (remote control) and so on.
